Try testing with carbide tipped boring bits. They come in 2 styles, a pointed thru drill and typical brad point. Some brands of plywood cut better with one or the other. 3000-5000 RPM. .75 to 2ips. All will cut good on the up side, adjust your feeds and speeds to get best back side

If this is going to be an ongoing project I'd start looking at an air drill.
